Referring to the drawings, it will be seen that theupper book 10 and the lower bunk 11 are detachahly supported upon a pair of rear stanchionslQ and 13 anda pair' ofiront stanchions. 1,4 and 1 5,.said stanchions comprising lengths oi heavy, steel or iron tubing, the endsof which are suitably secured to the floor and roof of the deck of the vessel, for-instance bymeans of sockets 16. In some instances. 95 course, it may be unnecessarlyl to provide a full ;set of stanchions for eac pair of bunks there being many cases in which it may be possible or desirable to use walls of the ships heenirem red i rm i s fiat. elevation of theounk Specification of Letters iatent.

hull, in place of the independent stanchions just mentioned.

In the preferred each bunk is equipped bottom which, in the present instance, coniprises a wire, link stretched or 'snnported in the bunk frame by means of helices 18. Preferably an independent transverse row of the said helicals 18 is providedat each end of the bed fabric 7 th es er e ds of the said hel e be ng hooked inthe apertures 19 punched in the horizontal web of an angle iron 20, the said angle irons 20 constituting the end hereof the frame which inclose the bed bottom. The side members of the bed bottom frame comprise a pair of parallel spaced apart steel or iron tubes :21 which connect the outer ends of the anglc bars 20 and in order to form an ellicient connection, the ends of the said snglehars 20 areequipped with small sccketrnembers 22. The said socket members 22 are furnished with logs 23' which are united torthe horizontal webs of the angle bars QOby means of rivets as shown at 24: and the outer ends of the said socket members 22 are aperturcd to sliclaloly receive the extremities of the side tnbcsEZL Preferably the sockets 22 are prerentedirom sliding toward each'othcr along the side tubes 21 by reason of therertical web '25 of the end bar constituting astopor abutment at the outer ends ofr'the apertures in the said sockets. In order to prerent the fabric from sagging unduly from the weight of the occupant, the bunk is equipped; witlrone or more flexible slat mernhersflfi the ends of which are connectcd to clamps 27 surrounding the side tubes by means of helicals 28.

The bank is hung or supported between the stanchionsll 13, 14 and 15 hr means of devices associated with .thecnds of the lee rails Qtlend fillsaid lee rails 29 and 30 be inghinged or pivoted to the side tubes 21 by means of a series of arms or rods 31, the ends of which are riveted into the said lee this land 30. In order to provide the necessary pivotal connections between the rods 31 and the side tubes '21. the, latter are made circular as shown and the rods 31 are equinpedat their ends with eyes loosely embrace or inclose ,the said side tubes 21.

' ln e idert form of my invention maintain the lee rails 29 and "fabric 17 resiliently.

32 which with a resilient bed 7 80 at the desired distance apart when the bunk is in effective use, I employ a pair of spacer tubes the ends of which are open and adapted to receive the heads of short studs 34 riveted into the ends of the lee rails 29 and 30. The ends of the studs 31 are, of course, suitably pointed so that they will readily enter the open ends of the spacer tubes The spacer tubes 33 are also pivotally connected to the frame of the bunk, this being accomplished by virtue of pairs of rods 35, the outer ends of which are riveted or otherwise secured into holes in the spacer tubes 33, the pivotal connection being effected by means of small angle brackets 36 riveted through the vertical web of the angle bars 20. The pivot pins 37 form the hinge connection between the lugs of the brackets 36 and the flattened perforated ends of the rods 35.

By means of the construction just described it will be manifest that the bunk til) may be collapsed as shown in Fig. 5 or 6 or it may be adjusted into the set-up or operative position as illustrated in Fig. 1. The means for supporting the bunk in the stanchions 12, 13. 14: and 15 comprise a set of stamped metal sockets 38, the outer ends of which are forked as shown at 39 in order to inclose the stanchions, rigid connection between the sockets 38 and the stanchions being effected by means of rivets 40 which pass through the stanchions and forked ends 39. The sockets 38 take the form of hollow cylinders the axes of which are horizontal, the upper surface of the said cylinders being cut away as shown best in Fig. 4 to admit the ends of the lee rails 29 and 30. The internal diameter of the sockets 38 is considerably greater than the external diameter of'the lee rails which are accurately located concentric with the sockets by providing the sockets 38 with integral end flanges 41 vertically slotted as shown at 42 to receive the ends of the lee rails and accurately position the same.

The ends of the lee rails are prevented from moving axially out of the sockets 38 by means of transverse studs or pins 1-3 extending diametrically through the ends of the lee rails and having projecting portions 44 substantially as long as the depth of the flanges 41. It is to be observed by reason of the aforesaid projecting portions 44 the ends of the lee rails are positively locked within the sockets 3S and cannot be accidentally displaced therefrom due to any springing apart or other movement of the stanchions 12, 13, 14 and 15. It will be observed also that the said pins 43 do not interfere with the swinging of the bunk into a vertical position as shown in full lines in the upper part of Fig. 1. while at the same time when the bunk is swung into vertical position, the pins 43 assume a horizontal position and thus positively prevent the ends of the lee rails from jumping out of the tops of the sockets 38.

When the upper bunk is moved into the full line position shown in Fig. 1. it is prevented i'roni dropping back into horizontal position by means of a pair of locking devices one of which is shown in Fig. 2. Said locking device con'iprises a small stamping preferably of inverted channel shape in cross-section, the vertical lugs 40 being spaced apart a suilicicnt distance to inclose the stanchions. Except as to its outer end -17, the said stamping is cut away on its upper side so that it may swing into the dotted line position indicated at 48 in Fig. 2. the rivet 49 which secures the locking device to the stanchion also serving as a pivot about which such swinging movement is effected. hen the bunk is to be swung up into vertical position. the locking device is lifted into the dotted line position so as to permit the upper lee rail to be moved into the desired position as shown in Fig. 1 after which the locking device 45 is released and falls by gravity into the position shown in Fig. thereby securing the bunk positively in vertical position. When the bunk is in the dotted line position, shown in Fig. 1,'the locking device 45 drops into the dotted line position 50 shown in Fig. 2.

I claim 1. The combination of a bunk provided with a pair of Ice rails the ends of the rear lee rail constituting pivotal supports around the axes of which the bunk may be rotated from horizontal to vertical position or vice versa; pins rigidly secured in the ends of said lee rails and so transversely positioned in the said ends that when the bunk is horizontal, said pins have their axes vertical and projecting downwardly and a set of stationary sockets for receiving the ends of said lee rails. the said sockets each comprising an axially horizontal cylinder slotted as to its upper side and having its end flanged over, the said flanged end being slotted to position the end of the lee rail, said pins being located within the flange of the said socket whereby the rail end is locked securely in said sockets against longitudinal movement.

2. The combination of a bunk provided with a pair of side rails. the ends of the rear side rail constituting pivotal supports around the axis of which the bunk may be rotated from horizontal to vertical position or vice versa; pins rigidly secured in the e ds of said rail and so transversely positioned in the said ends that when the bunk is horizontal, said pins have their axes vertical and projeetin downwardly. and a set of stat onary socficts for receiving the ends of said side rails. the said sockets each comprising an axially horizontal cylinder slotted as to its upper side and having its end flanged over, the said flanged end being slotted to position the end of the side rail, said pins being located Within the flange of the said socket whereby the bunk is locked securely in said sockets, the diameter of the end of the side rail in said socket being considerably less than the internal diameter of the said socket thereby permitting rotation of said pins within the said sockets when the bunk is swun on its pivotal axis.

3. The COII13ll13tlOI1 of an upright, a bunk pivotaliy supported thereby and provided with a projecting male pivot member having its axis horizontal, a socket on said upright having an opening for receiving the end of said pivot member, said opening having an upper entrance for admitting the end of said pivot member, and a side aperture communicating with said entrance, the bottom of said aperture constituting a pivotal support for said ivot member, said pivot memher having Within said socket an outwardly projecting part normaliy projecting downwardly when the bunk is in horizontal or operative position for preventing Withdrawal of said pivot from said socket horizontally, and also constitutin means for preventing upward movement 0 said pivot member out of said entrance when the bunk is swung into abnormal or vertical position.
